The aim of this research is to evaluate Support Vector Machine method (SVM) for identifying Pecan Weevil among other insects. Eventually, this recognition system will serve in a wireless imaging network for monitoring Pecan Weevils. Approach: SVM has been evaluated using two different kernel functions i.e., Polynomial Function and Radial Basis Function. Database of 205 Pecan Weevils and 75 other insects which typically exist in pecan habitat has been used. Three sets of input data for SVM have been generated by two standard region-based recognition methods. These sets are comprised of output obtained by Zernike Moments, Regional Properties and combination of these two methods. For each kernel function, the system had been trained by 25, 50 and 75% of data and remaining ratio in each case has been used for testing. Each experiment is repeated ten times and average results are considered for comparisons and analysis. Results: The optimum recognition rate had been found when system is trained by 75% of data. The results are approximately similar when the input data is obtained by Regional Properties and combination of Regional Properties and Zernike Moments methods. The optimum results are obtained when input data has been obtained by Zernike Moments alone for lower values of sigma 's'. The proposed system is able to successfully recognize 99% of Pecan Weevil and 97% of the other insects using the radial basis function. The proposed system took approximately 31 sec for processing 75% of the data which include the time for training. The testing time is found to be 0.15 sec. Conclusion: Promising results can be obtained when input data is obtained by Zernike Moments and SVM is trained by RBF and 75% of data.10aCurculio caryae1 aHassan, Ghulam, Mubashar1 aAl-Saqer, Saleh, Mufleh  uhttps://weevil.myspecies.info/pecan-weevil-recognition-using-support-vector-machine-method01544nas a2200181   4500008004100000020001400041245010600055210006900161260000800230300001400238490000800252520088200260653002001142100002301162700002201185700002501207856013001232       2010                        eng d  a0022-049300aDNA Identification Confirms Pecan Weevil (Coleoptera: Curculionidae) Infestation of Carpathian Walnut0 aDNA Identification Confirms Pecan Weevil Coleoptera Curculionida  cAug  a1312-13140 v1033 aLarvae found infesting fruit from a Carpathian walnut, Juglans regia L., tree in Missouri were confirmed by DNA analysis to be those of pecan weevil, Curculio caryae (Horn) (Coleoptera: Curculionidae). The infested walnut tree occurs in the midst of pecan weevil-infested pecans, Carya illinoinensis (Wang.) K. Koch; the larval haplotypes were found to be identical to pecan weevil larvae from the region, indicating that the walnut infestation arose by association with infested pecan. This is the first confirmed DNA analysis showing pecan weevil attacks J. regia and the second report that J. regia may be at risk of infestation by pecan weevil. Further study indicates this infestation on walnut is established and ongoing. The pecan weevil is a key pest of pecan and seems capable of inflicting similar damage to walnut if spread to commercial areas that produce J. regia.10aCurculio caryae1 aHarris, Marvin, K.1 aHunt, Kenneth, L.1 aCognato, Anthony, I.  uhttps://weevil.myspecies.info/dna-identification-confirms-pecan-weevil-coleoptera-curculionidae-infestation-carpathian-walnut02231nas a2200169   4500008004500000020001400045245007400059210006900133260001300202300001200215490000700227520166400234653002001898100002201918700002001940856010101960       2008                        Engldsh    a1461-955500aMovement of adult pecan weevils Curculio caryae within pecan orchards0 aMovement of adult pecan weevils Curculio caryae within pecan orc  cNovember  a363-3730 v103 a1 The pecan weevil Curculio caryae (Horn) (Coleoptera: Curculionidae) is an indigenous pest of pecan Carya illinoinensis (Wangenh.) K. Koch, in North America. Understanding the movement of this pest from the orchard floor to host trees could lead to pest management practices that exploit weevil behaviour and thus reduce insecticide application to the entire orchard canopy. Furthermore, no information exists on diel periodicity of pecan weevil movement.2 Movement of adult pecan weevils crawling and flying to the host trunk, flying to the host canopy, crawling within the host canopy and flying between host trees was studied using four types of passive traps over four seasons. Each type of trap was used to capture weevils at different locations on or near the tree and to discriminate flying versus crawling behaviour.3 More pecan weevils crawl to the trunk than fly and a proportion of the population flies directly from the orchard floor into the pecan canopy. The majority of this movement occurs at dusk.4 The vertical distribution of weevils was generally uniform throughout the canopy but more weevils were captured in suspended traps nearest tree tops, rather than traps near the ground, when flying between trees and this was significantly so for two of 4 years.5 The results of the present study are contrary to previous reports suggesting that most adult pecan weevils fly to the pecan trunk after emergence from the soil; however, our results did indicate that a proportion of the population flies directly from the orchard floor into the pecan canopy and thus would circumvent strategies that attempt to control weevils moving up the trunk.10aCurculio caryae1 aCottrell, Ted, E.1 aWood, Bruce, W.  uhttps://weevil.myspecies.info/movement-adult-pecan-weevils-curculio-caryae-within-pecan-orchards
